Resizing windows is very sluggish.

Could it be my video cards? I'm currently using SLi'd 7900GTXs while waiting for an RMA on my 8800GTS 512.

edit: scrolling is also slow.

sounds like the video drivers aren't installed, or atleast, aren't installed correctly.

Reinstall the video drivers

Reinstalled twice. Time to break out driver cleaner, I guess.

Edit: Weird. Left to it's own devices for a few hours and the problem is gone.

That's weird, i would think it would be the drivers as stated.
